CTM 1 / CTM 2

Liquid Ejector is a part of the CO2 Adaptive Liquid Management (CALM), Danfoss' solution to handle liquid in all types of transcritical CO2 systems in all climates. Due to higher suction pressure, Liquid Ejector, together with Adaptive Liquid Control (ALC), enables lower energy consumption and better utilization of evaporators, resulting in operational savings. Improved system performance results in fewer or smaller compressors and a minimal suction accumulator. Liquid Ejector is designed for CO2 transcritical systems to pump the CO2 liquid from the low point in the suction accumulator back to the receiver resulting even in 8 bar pressure lift after mixing with gas coming from the gas cooler. The Liquid Ejector, AK–PC pack controllers, AKCC case controllers, and AK–SM system manager comprise the Danfoss CALM.

Features and benefits

  • First Cost savings• Lower cost compared to standard booster system due to lower swept volume of compressors (i.e. smaller compressors or less number of compressors)
    • Reliable and robust design
    • Fully integrated solution not requiring any additional components like check valves or motorized ball valves
    • Fully serviceable – wide range of spare parts and accessories
    • Easily accessible strainer / filter for fast maintenance
    • Brings first cost savings
    • Enables 5 – 10 % savings on compressor swept volume, compared to standardbooster systems
  • Fast Pay Back – Energy saving• Improved COP and lower swept volume to the MT compressors, resulting in lower energy consumption
    • Savings for end users
    • Fast payback – lower energy consumption
    • Less compressors and higher efficiency on the systems, leads to shorter payback time of less than 2 years on avarage globally
    • The combination of CTM 1 and CTM 2 Liquid valve and the Danfoss CALM controllers ensure an easy setup and commissioning, robust control of the system that ensures many years of problem free operation
